To solve this problem you must apply the proccedure shown below:
1- The problem says that you are swimming each 25 yard length 3 seconds faster than your personal best and you have to calculate the change in time (which you can call
) of your personal best after 200 yards.
2- To calculate this, you must multiply 200 yards by 3 seconds and divide by 25 yards, as following:

Therefore, the answer is: 24 seconds.
Answer:
It should be 75 inches
Step-by-step explanation:
Answer:
14/20 or simplified 7/10 it can also be shown as 70% or 0.7 or 0.70
Step-by-step explanation:
The way to get the equation for the radius (r) is to get r by itself. So divide each side by 4pi
500/4pi=r^2
Now take the square root of each side to get the equation of r.
sqrt(500/4pi)=r
200, because 8% is 8 parts of 100%. Then 1 part of that 100% is 16/8=2. Then 100% is the number i.e; 200
